I disagree.

Note, I responded because I assumed this was a new Linked Data service. 
But it clearly isn't. Thus, I don't want to open up a debate about 
Linked Data virtues if you incorrectly assume they should be *demand 

Remember, this is the Linked Open Data (LOD) forum. We've long past the 
issue of *demand driven* over here, re. Linked Data.

See my comments above. I also encourage you to browse through some of 
the older threads here and elsewhere re. Linked Data.
